Hi, I have 2 mounts for my 2 monitors, but they're different. One is long, and has a peg that goes through a slit, like this:

Long mount.

The other is a simple mount, like this:

I find the simple one makes the monitor too low. I prefer the long one, but I can't find it anywhere in the ergotron catalog. The long one came with my ergotron. I would like to find another long mount.
